Rubber plant (Ficus elastica)

Karet kebo or rubber plant (Ficus elastica) is a species of plant in Moraceae, parenial, tree up to 30 meters high, trunk diameter up to 2 meters, has hanging roots as anchors in the ground and helps support the weight of branches.

F. elastica has a brown taproot and aerial roots. Stem erect, cylindrical, branching simpodial, bark surface rough and dark brown.

The leaves are arranged alternately, oval in shape, thick, flat edge, tapered tip and base, green or black, 10-35 cm long, 5-15 cm wide, leaves on young plants sometimes have a length of up to 45 cm.

Humpback whales (Megaptera novaeangliae) manufacture bubble-nets as tools to increase prey intake

NEWS - Humpback whales ( Megaptera novaeangliae ) create bubble net tools while foraging, consisting of internal tangential rings, and actively control the number of rings, their size, depth and horizontal spacing between the surrounding bubbles. These structural elements of the net increase prey intake sevenfold. Researchers have known that humpback whales create “bubble nets” for hunting, but the new report shows that the animals also manipulate them in a variety of ways to maximize catches. The behavior places humpbacks among the rare animals that make and use their own tools. “Many animals use tools to help them find food, but very few actually make or modify these tools themselves,” said Lars Bejder, director of the Marine Mammal Research Program (MMRP), University of Hawaii at Manoa. “Humpback whales in southeast Alaska create elaborate bubble nets to catch krill. They skillfully blow bubbles in patterns that form a web with internal rings. They actively control details such ...

Plumeria rubra and Plumeria obtusa, the differences

SPECIES HEAD TO HEAD - The genus frangipani trees ( Plumeria Tourn. ex L.) has only 18 officially recorded species and two very similar species, frangipani ( Plumeria rubra L.) and white frangipani ( Plumeria obtusa L.). Both have the same habitus, flowers and fruits and are difficult to distinguish. The leaves of both species have slightly different shapes. Therefore, the leaves are very important to distinguish the two species, especially the shape of the tip. P. rubra has simple, lanceolate leaves with acute tips. P. obtusa has simple, elliptic leaves with rounded tips. By Aryo Bandoro Founder of Dlium.com . You can follow him on X: @Abandoro . Read more: Plumeria rubra Plumeria obtusa
